Even though we do have a lot of utility moves I feel that they are necessary. We do not have a knockback, most of the time when healing we can't use sleep dart, and the invisibility is used just as an OSHT button. Those that play operatives know that we are squishy if say a marauder or an assassin comes out of nowhere and pounds on us. Being a healing operative on a server that is fairly active in pvp, I will say that when it comes to our utility moves it's all about timing and situations. My two cents.
